HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 767,795, dated August16, 1904. Application filed December 23, 1902. Serial No. 136,410. (Nomode To all whom, it may concern.-

Be it known that I, ANDRE OAs'rELIN, a citizen of the French Republic,residing at 17 Rue St. Florentin, Paris, France, have invented certainnew and useful Improvements in Mowing and Reaping or HarvestingMachines, of which the following is a specification.

This invention relates to harvesting-machines.

The object of the invention is to provide an efficient machine which maybe used either for mowing or reaping or for harvesting.

The present invention is adapted to effect I 5 accumulation andcompression of the material by separate mechanisms, and it effects theplacing on the ground of a sheaf that is as compact as possible withoutbeing bound, the material being ejected at intervals of time regulatedwith the density of the cropor with the size of the sheaves.

For the purpose of the invention I provide a novel mechanism by which aseries of rakes are provided for effecting the accumulation of thematerial, which rakes are lowered during a portion of the operation andare then raised and held in an elevated position while the material,which has been accumulated by the rakes in their lowered position, isejected. In the accompanying drawings, Figure 1 is a plan of the wholemachine. Fig. 2 is a section on the line A B, Fig. 1. Fig. 2 is a viewshowing in detail the oscillatingdevice of Fig. 2 in its secondposition. Fig. 3 is a 3 5 detail top plan view of a portion of themechanism represented in Fig. 2, the deck or platform of the machinebeing omitted. Fig. t

is an elevation (as seen from the interior of the machine) of partscomprised in Fig. 3. 4 Fig. 5 is a section on the line C D of Fig. 1seen from the right-hand side. Fig. 5 is a detail bottom plan view. Fig.6 is a section on the line E F of Fig. 1. Fig. 7 is a section on theline G H of Fig. 1, and Figs. 8, 9, and

10 show separately details of some of the parts in Figs. 5 and 7. Figs.11 and12 show in detail a system of adjustment by universal joints forthe rod operating the cutter-bar of the machine. Figs. 13 to 16,inclusive, are longitudinal sectional elevations of the platform ortable of the machine, showing particularly the action of the rakemembers and certain of their associated parts.

According to this invention the moving device for transporting thematerial or crop toward theend of the platform or table 12 consists oftwo chains 1, moving parallel to each other and operated by two pinions2 and passing over guide-pinions 3 at the right of the machine. Thedriving of the machine, which may be operated either mechanically or byanimal-traction, comprises a main shaft 4:, carrying an endless screw 5,transmitting motion to achain 6, which operates the releasing mechanismhereinafter described. The shaft 4 is in connection with a countershaft4, which operates the chains 1 by toothwheels 7 7, and the shaft 4'carries at one of its ends the crank 8, which drives the cutterbar ofthe machine. The chains 1 are connected to each other by two rods 9,arranged at points dividing the chain into two equal parts. These rodsare formed of tubes connected to a link on each chain in such amanner asto turn freely. For this purpose the link carries a sort of trunnion 10,in which the end of the tube engages, as shown in Fig, 3.

The tubes 9 carry a series of rake-teeth 11,

, which project above the platform 12 of the machine, which is groovedor slotted throughout its length in order to give them passage. Thesegrooves are shown by the dotted lines 13 in Fig. 1.

At the end of the platform curved arms 14:, (shown in Fig. 5,) which Iterm accumulators, are employed, against which the material is presscdas it is pushed forward by the teeth 11 of the rakes. Since the presenceof the material thus pressed would prevent the rakes reaching the end oftheir course, and, on the other hand,- it is necessary for allowing theejection of the material to allow the teeth of the rakes to go to theend of the platform, an arrangement is provided enabling these teeth todescend to beneath the platform at a certain distance from the endduring the accumulation of the material and to project when the ejectionis to take place. For this purpose the rakes carry on one side a smalleleat 15, Figs. 2 and 3, having a friction-roller 16 at one end whichmoves along a guide 17, consisting of a U-shaped rod, of iron, fixed tothe wooden girder 18 of the machine. At the place where the teeth 11should be lowered or depressed this grooved rod is joined by a part 19,constituting a switch jointed at 20.

The axis is connected by a link 21, connecting the crank-arms 85 and 86on the shafts 20 and 22 to an axis, Figs. 4 and 5, which extends fromone side of the machine to the other, passing under the table whichsupports it. When the part 19 is in the position shown in Fig. 2, if therake be displaced in the direction of the arrow F the friction-roller 16will be deviated from a straight line while passing along the groove 17and a partial rotation will be imparted to the tube 9, which carries it,and the teeth 11 will be inclined, so as to come under the platform. Tosecure the complete lowering of these teeth, I arrange below the plate12 an arm 23, attached to a spring 24, fixed to the girder, 18 andhaving a tendency to draw it in the direction of the arrow shown in Fig.3. On the axis 20 a linger is fixed, which when the links 21 occupy theposition shown in Fig. 4 rests on an inclined plane 26 of thespring-pressed arm 23, so as to thrust it inwardly. When the links 21are lowered, the finger 25 releases the arm 23, which is drawn outwardlyby the spring 24, and thus allows the teeth of the rake, which remainprojected above the platform, to pass freely.

At the end of the groove in the guide 17 are spring-actuated plates 26,the springs of which serve to normally hold the plates in theireffective positions to close the discharge end of the groove. In otherwords, the plates constitute switches, and when they are engaged by therollers 16 the latter deflect or thrust the plates or switches downward.As soon as the rollers pass out of contact with the switches they areinstantly returned to their initial positions by the power of thesprings thereof, thereby to prevent the return of the roller into thegroove. At the opposite end of the groove 17 is situated a channeledplate 27, (see Fig. 2,) the channel of which registers with the widenedentering end of the groove in the guide 17 and is arranged to receivethe rollers 16 during the travel of the rods 9 around the pinion 3,thereby to elevate the fingers to a position above the slotted platformof the machine. Supplemental or auxiliary fingers 28 operate inconnection with the pressing-fingers 11 and are adapted as the rollersenter the channel of the plate 27 to travel along the edge of said plateto thereby prevent lateral motion ofthe fingers 11.

In order to secure the passage of the roller 16 from the channel 27 tothe groove of the guide 17-that is to say, in order to prevent it fromescaping from the space which must necessarily exist between these twoparts-a finger 28 is provided on the rod 9, which finger bears under theaforesaid plate and keeps the rake in position. To cause the dischargeof the material to take place at intervals of time varying according tothe density of the material, oscillation of the part 19 must be producedat variable intervals of time, and this is effected by the mechanismshown in detail in Figs. 5 to 10. On a fixed cross-bar-29 of themachine, Figs. 2 and 7, supported on one side by a support 30 and on theother side by a support 31, slides a tube 32, terminating at one end ina hand-wheel 33 and atthe other end in the integral enlargement 34,provided with a catch or finger 35. Within the enlargement 34 a spring36 is arranged, said spring bearing at one end on the washer 37,suitably fixed to the shaft 29, (see Fig. 10,) and at its opposite endagainst the plate or washer 38, closing the open end of said enlargementand rigidly connected therewith. The plate 38 is free of said shaft,from which it will be apparent that when the sleeve 32,

and naturally its integral enlargement, is

drawn toward the right in Figs. 7 and 10 said spring will be compressedin order that on the release of the hand-wheel 33 the spring will returnsaid sleeve to its original position. To facilitate this movement, afixed wheel 39, serving as a rest, is arranged behind the Wheel 33, thetube 32, with its sleeve 34, turning freely on the cross-bar 29. At theside of the sleeve 34 is placed a cam 40 with afinger 41 and a notch 42for receiving the catch or finger 35 of the sleeve 34. At the side ofthis cam is placed a wheel 43, which, for example, is a wheel withthirteen teeth arranged like a wheel of twenty-six teeth with everyalternate tooth suppressed. This wheel is opposite a cam 44, placed onthe shaft45,-so that it makes a thirteenth portion of a turn for a turnof the shaft 45. In the face of the Wheel 43 are arranged thirteengrooves 46, in which the finger 35 of the sleeve 34 can also engage, andthis finger should have a suificient length to enable it to penetrateinto these grooves after having passed through the notch 42 of the cam40. The course of the tube 32 over the cross-bar 29 should besufiiciently limited to prevent the finger 35 being released from thenotch 42. In other words, the length of the finger 35 is such that itwill not leave the notch 42 when the tube 32 is slid outward along thecross-bar or shaft 29. The wheel 43 is made with a ratchet 47 alsohaving thirteen teeth. This ratchet, which can turn freely on thecross-bar 29, (as well as the wheel 43 and cam 40,) is connected to thesaid cross-bar by a spiral spring 48, and the said ratchet carries afinger 49, bearing on the fixed abutment 50, arranged on the support 31.When the ratchet 47 is no more in gear with its pawl 51, under theaction of the spring 48 it takes the position shown in Fig. 5. The cam44 is arranged in relation to the wheel 43 in such a manner as to causeit to advance a little more than one-thirteenth of a turn, so that theratchet 47 at each displacement which follows this movement shalladvance one tooth in relation to the pawl 51, with which it'is in gear.On the axis 87 of the pawl 51 is a lever 52, one end of which carries africtionroller 53, against which the finger 41 of the cam 40 bears. Thepawl 51 carries a finger 54, which bears on the lower face of the lever52, so that when this lever is lowered under the action of the cam 40 italso lowers the pawl 51 and releases it from the tooth of theratchet-wheel 47. The pawl 51 is connected by a spring 55 to a fixedpart of the machine. The lever 52 is connected by jointed rods 56 57 tothe axis 22, Figs. 4 and 5, which operates the crank-arms 85 and 86,connected by the link 21, itself connected to the oscillating part 19.The operations of this portion of the mechanism is as follows: Theposition of repose of the ratchet 47 is shown in Fig. 5. By means of thehand-wheel 33 theposition of the finger 41 of the cam 40 can beregulated with regard to the friction-roller 53. If, for example, thesetwo parts be separated a distance corresponding to six teeth of theratchet or six notches of the wheel 43, the finger 41 and the roller 53will come into contact after the sixth turn of the shaft 45, (or the cam44.) As the wheel 43 advances, and with it the ratchet 47, the spring 48is wound up or tensioned. When the tooth 41 lowers the roller 53, itreleases the pawl 51 from the ratchet 47, and this latter under theaction of the spring 48 resumes its original po-- sition, and since thisratchet is sleeved onto the wheel 43, which is itself secured to the cam40 and the sleeve 34 by the finger 35, the mechanism will return to itsinitial position after each release. At the moment of release the rod 56is raised and communicates, by means of the lever 57, axis or shaft 20.and link 21, an oscillation to the part 19, which assumes the positionshown in Fig. 2, which leaves a free passage for the friction-roller 16toward the end of the guide 17; but as soon as the said roller meets thesecond portion of the part 19 it brings it to its original position. Itis thus the part 19, which raises the crankarms 85 and 86, connected bythe link 21, acts on the axis or shaft 22 and rod 56, and brings thelever 52 back into its original position. The pawl 51, as clearly shownin Figs. 5, 5, and 7, is pivoted on the stud 87, on which is alsopivotally mounted the lever 52, which car-' ries the roller 53. Saidpawl 51 carries on its lower part a finger 54, bearing on the lower faceof the lever 52. When the finger 41. of

the cam 40 bears against the roller 53, the lever- 52 is lowered. Thepawl 51 is simultaneously lowered through the finger 54 and disengagedfrom the ratchet-wheel 47 until the finger 41 isfree of theroller 53.The mechanism is then ready to start again. In order to retain thecrank-arms 85 and 86, connected by the link 21, in their extremepositions, a small bolt, such as 58, worked by hand, is provided, placedat or about one of its ends. The bolt 58 is hand-operated when itbecomes necessary to either raise or lower the levers 85 and 86. Whenthe release of the mechanism takes place, the discharge of the materialor crop commences and at the same instant the accumulators orcompressors 14 must be raised. They are connected to the releasemechanism, which consists as follows: The accumulators consist ofbranches 14, fixed to a shaft 59, supported by a cross-bar 60 on theframe of the machine. One end of the shaft 59 is connected by a rod 61,Fig. 5, and crank-arms 61 to a ratchet 62, secured to the axis 63. \Viththis ratchet gear two pawls, one, 64, (whose head forms a bolt,) beingconnected by arod 65 to the lever.52. The other pawl, 66, is kept ingear with the ratchet by means of a spring 67 and is mounted on the axis68, which traverses the girder 18. This axis carries a finger 69, whichis in the path of the rod 9 of the rakes. When the rods meet thisfinger, (being displaced in the direction of the arrow shown in Fig. 6,)the pawl 66 is released from the ratchet 62. The pawl of the lever 52being then lowered acts at the same time on the rod 65, which presses onthe pawl 64 and causes the ratchet to advance, and the rod 61 moves andraises the accumulators 14, and these are kept raised by the pawl 66,which remains in gear with the ratchet 62. When the rod 9 strikesagainst the finger 69, the ratchet 62 is set free and the accumulators14 drop down again. All these release movements are operated by theshaft 45, which receives its motion from the transmission-chain 6, Fig.2. This shaft by means of bevel-gear 7 O operates the beaters 71, theposition of which may be regulated by any knownor suitable means.

This .machine is intended to mow or reap material of various kinds. Forcereals with long stalks the alinement must be retained during theirtransport to the platform. If they are caused to lie down while makingthem oscillate round the point 74 of the reaper, Fig. 7, the movement ofthe reaper or cutter deranges the alinement and entangles the crop. Inorder to remedy this defect, the following arrangement is adoptedaccording to this invention: The'inclined plane 75, which extends fromthe cutter 74 to the platform or table'12,

is jointed to this latter in such a manner that it can be raised. Feet76 under this inclined plane enable it, for reaping, to be kept in theraised position shown-by the dotted lines at Fig. 7.. The arms of thebeater 71 will cause the stalks to lie on the platform, they turning onthe point 77. The lower ends are thus immediately separated from thecutter and their alinement is not interfered with. When mowing, theplane 7 5 is left in its lowered position, and the height of the beater71 is so regulated that its arms come level with the cutter-bar and keepit free. Fig. 1 shows on each side of the knife points 78 and curvedplates 7 9, which make way through the material and facilitate theforward. movement of the machine, which it will be understood takesplace in the direction of the arrow F Fig. 1. The cutter 88 is operatedby a crankplate 8 and rod 80. A system of universal joints is employedfor the connections of this red. This is shown in detail in Figs. 11 and12 and consists in fixing at the two ends of the rod 80 plates 81,between which the sleeve 82 can oscillate. The sleeves 82 turn freelythe one on the pin of the crank-plate 8 and the other on the trunnion 83at the end of the cutter-blade. A bolt or pin 8a keeps each sleeve inposition. A universal joint is thus obtained which perfectly transmitsmovement while bending itself to all deformations to which the machineis subject.

Having now particularly described and ascertained the nature of myinvention and in what manner it may be carried into effect, I declarewhat I claim is 1. In a machine of the class described, the combinationof a deck, a rake for feeding material along said deck, a switchcooperative with the rake and serving when traversed by the rake toshift the latter into an ineffective or non-feeding position,accumulators for momentarily arresting the passage of material from thedeck, and mechanism for simultaneously shifting the switch andaccumulators, the switch being shifted into position to throw the rakeinto its feeding position, and the accumulators into a position torelease the accumulated material on said deck.

2. In a machine of the class described, the combination of a slotteddeck, a pair of feedchains supported for traveling movement under saiddeck, rake members pivotally carried bysaid feed-chains, the workingportions of which are arranged to extend upward through said slots, aswitch located in the path of the rake members and adapted normally toshift said rakemembers into an ineffective position, accumulators at theend of the deck, and mechanism for simultaneously operating the switchand the accumulators, the switch being moved into a position to throwthe rake members into their working position and to move the accumulators into position to permit the release of the accumulated materialon the deck.

3. In a machine of the class described, the combination of a deck, arake for feeding material along said deck, a switch for controlling theposition of the rake, a lever, connections between the lever and theswitch for shifting the latter, a cam for operating the lever,accumulator-arms at the end of the deck,a ratchet connected with theaccumulator arms for shifting the same into a position to release theaccumulated material on the deck, and a pawl operable by the said leverfor actuating said ratchet.
